IMPROVEMENT lN FLOUR-BOLTS.

Specification forming part of Letters Patent No. 35,953, dated July .22,1862.

T0 aZZ whom it may concern.-

Be it known'that I, HENRY .REIOHERT, of Shippensburg, in the county ofCumberland and State of Pennsylvania, have invented a certain new anduseful Improvement in Flour- Bolts for Separating Flour from Bran; and Ido hereby declare that the following is a full,

confined more particularly'to the improvement which forms the subject ofthis patent.

In the drawings, A represents the shaft of the bolt, from which projector extend the arms B B, to which are fastened the bars C O, whichsupport the bolting-cloth D. To the inside of the arms C O are fastenedmetal spring-bars E. These metal spring-bars are caused to suddenlyvibrate at each revolution of the bolt by means of the metal slidinghammers F, which pass loosely through the shaft A, whereby as the boltrevolves the sliding hammers are constantly falling down upon thespring-bars while the latter are passing their lowest point, thuscausing the bars 0 G to have a constant and quick vibration, which isimparted by said bars to the bolting-cloth.

' In order that the upper arms and the bolting-cloth which covers themmay be vibrated at the same time the lower ones are, the springarms E onone side of the shaft A are connected to those on the opposite side bymetal rods or straps G G, whereby the vibration caused by the fall ofthe sliding hammers is imparted to the bolting-cloth both above andbelow the shaft. The number of spring-arms and hammers will depend uponthe size of the bolt employed. By this arrangement the meshes of thebolting-cloth are kept clear, especially of the conicalshaped particles,which often fasten in the meshes of the bolting-cloth and occasion muchdifticulty. By my improvement they are thrown out of the meshes and passoff with the bran.

The sliding hammers F are regulated by adjusting-plates H, through whichthey pass.

The plates H are to be confined to shaft A by means of screws a a, orsome other proper fastenings which will permit the plates to slide in ahorizontal position. In this instance the plates are slotted out, asseen at b. 1), Figs. 1 and 2.

One end of each plate H is connected to a rod, I, which passes through ahole in an earpiece, J, fastened to shaft A, after which a spiralspring, 0, is passed upon its end, and

can be made at one end of the bolt, and even when the bolt is inoperation, by simply hav' ing a door or slide at the end of the box inwhich the reel or bolt revolves.

My improvement is simple in construction, but very effective inoperation.

Having described my improved flour-bolt, what I claim, and desire tosecure by Letters Paqent, is-

1. The combination of the bars 0 G, and sliding hammers F, andadjusting-plates H, substantially as set forth.

2. The combination of the rods or straps G G with springarms E, hammersF, and arms G O, as and for the purposes set forth.
